The concept of Software-as-a-Service (SaaS) has established itself:

• Delivered on the web• Hosted”, or on an Intranet• Web-based data storage

– As done in present web-based mail systems

• Simplifies systems management

– ”The terminal” is back!


!��

• If something can be done on the web, it will be done there.

• The web will be the natural space for IT.• Traditional IT will be ”webbified”.

• Old types of services and functions, but also completely new ones

• New types of actors, with new types of business models and business processes


��

• Disruptive technology:– “technological innovation, product, or service

that eventually overturns the existing dominant technology or product in the market”

• Examples:– Vacuum tubes � transistors– Mainframes � minicomputers– Minicomputers � personal computers– Video tape � DVD

– PC as platform � the web as the platform

– participate ... producers– cooperate– communities are born and grow up– technology offers new user experiences– ...

• Business:– users generate value– new types of business, – new possibilities


�� '��

• Active participation – who is producer, who is consumer?– Blogs– Wikis– Recommendation systems

• Tagging resources/objects– Direct value for users

• “Folksonomy” – community use of tagging– New conceptualizations

• Blogging– The value of being linked to– The value of being commented on

• Mashup/Remix– The value of reuse

• Exploiting patterns of usage– Votes, recommendations

• AJAX (first coined 2005): – ”Asynchronous JavaScript and XML”

• Set of technologies:– CSS, – JavaScript, – XML, – XMLHttpRequest

• Existing technologies used in new ways– Pushing the limits of what present implementations support– Create attractive user experience!


!��&��

• Styling in webbish ways, not like glossy magazines– CSS

• Dynamic visual modifications, no page loads– DHTML, JavaScript, DOM

• Context sensitive user options, no server checks– DHTML, JavaScript, DOM

• Asynchronous data fetch, no bulk data (re)load from server– XMLHttpRequest

• Behave like a desktop application!


!�� '� $��&��

• Industrial AJAX toolboxes:– GWT, Oracle, SAP, ... Dojo Foundation, ... – Support authoring/programming AJAX sites

• Based on existing and emerging standards!:– [X]HTML, RSS, Atom, FOAF, .....– HTTP, Atom (WS: SOAP, ...)

• ... the infrastructure of the web is what is needed!

• World Wide Web Consortium (1994- )• Industry consortium – specifies webbstandards• Approx 400 members – industry, public sector,

• Produces starndards (”W3C Recommendations”) i via a consensus-based process– HTML, HTTP, XML, .....

• External web 2.0– The Web 2.0 landscape ”out there”– How our user / customers / clients see us– What will attract / satisfy users?– Future users – the Net Gen!

• Internal web 2.0– The IT landscape ”in-house”– How we support our employees– How do we support our employees?– Future employees – the Net Gen!

• Don’t design for users – let users design for themselves– E.g., mash-ups

• Enable users to profile objects– E.g., tagging

• Support community building– E.g., tag sharing, folksonomies

• Find ways of capturing new values– E.g., community-based recommendations

• Traditional knowledge management – does not work

• Community-based knowledge management– Critical component: usage knowledge– Emerges through practical use– Concept models created by community– Handles dynamic trends ... ”usage drift”– Supports reuse of information and of experts

• Key innovation areas, such as:– Social bookmarking– Information dynamics

�� '��

• Users optimise value through communities• Communities emerge, they are not designed• Technology can support community building and

community life

• What external communities do you serve?• What internal communities do you have?
